Can't update Kernel since 4.14.3-1

Hallo,
I am currently having issues when trying to upgrade my kernel. I had to boot into a live system and downgrade back to 4.14.3-1 several times now, after trying to upgrade the kernel.

When rebooting after the kernel update the system seems not to boot fully. It hangs after the last boot entry, which seems to be successful though. So it hangs when SDDM (service enabled on boot) tries to start. I can't even switch to ttyX, the system (or at least the display) is completely frozen. My suspicion is it has something to do with the nvidia drivers, I am currently using nvidia-beta 387.34-1 (GTX 1060 GPU) , I do not really remember why but there was some reason for why I am using the beta drivers (I had to compile some stuff myself to get CUDA support for tensorflow).

Also sometimes the same thing seems to happen randomly while the system is running on the 14.3 kernel too. The display freezes completely while music keeps playing. I am using KDE.

Any suggestions? I may try to disable the SDDM service on boot and see if that gets me to tty1 after the kernel update, but still if that works I would have no idea of how to proceed.

This is the correct approach. From the console you can read the previous boot's journal and your Xorg log.

Moving to NC...

Thanks, I managed to fix the problem. It was indeed just the display not working as I suspected. I simply reinstalled the nvidia drivers after updating the kernel (without starting X). After another reboot everything worked again.

For some reason though my python dlib package (manually compiled with CUDA support) stopped working now, so I'll just compile and install that again too.
